Numerical simulations for the antenna-assisted subwavelength ohmic metal–semiconductor–metal (OMSM) structure made of gold and InSb. Excitation of localized SPPs, the 2D distributions of E 2/E 0 2 in x–y (z = 0) and x–z (y = 0) planes, and distribution of E 2/E 0 2 along the red dash (half width) line for the incident 0.151 meV photons in a a bare InSb slab (L = 150 μm, W = 50 μm, and t = 10 μm), b the subwavelength Au–InSb–Au structure (the same InSb slab with s = 90 μm), and c the antenna-assisted subwavelength Au–InSb–Au structure with s = 90 μm
